SPRAYED CONCRETE OPERATOR CERTIFICATION
In order to increase safety, enhance quality and minimize sprayed concrete waste, AMA Anläggning (Swedish standard) now states that all operators that will perform concrete spraying in tunnel projects shall have a certificate. This means that projects like E4 Stockholm Bypass (E4 Förbifart Stockholm), the New Subway (Nya tunnelbanan) and the West Link (Västlänken) require the certificate. The Swedish Rock Engineering Association (Svenska Bergteknikföreningen) is the certifying body and they will certify all operators that goes through and passes a training and assessment program including both a Theory part and a Practical part, as well as hands in a proof of spraying experience. The certificate is valid for 5 years. Edvirt® is accredited to hold both parts in the program - see "‘Theory part"‘ and ‘Practical part’ below.
Note: There is now also a certificate for Site managers and Construction managers. It’s however the same course required for it.
